Declassified U.S. Government Report Prepared a Week After Fukushima Accident: “100% of The Total Spent Fuel Was Released to the Atmosphere from Unit 4”
from Washington’s Blog We reported in 2011 that the International Atomic Energy Agency knew within weeks that Fukushima had melted down … but failed and refused to tell the public. The same year, we reported in 2011 that the U.S. knew within days of the Fukushima accident that Fukushima had melted down … but failed to tell the public. We noted in 2012:
Now, a declassified report written by the U.S. Nuclear Regulatory Commission on March 18, 2011 – one week after the tidal wave hit Fukushima – states:
The source term provided to NARAC was: (1) 25% of the total fuel in unit 2 released to the atmosphere, (2) 50% of the total spent fuel from unit 3 was released to the atmosphere, and (3) 100% of the total spent fuel was released to the atmosphere from unit 4.
NARAC is the the U.S. National Atmospheric Release Advisory Center, located at the University of California’s Lawrence Livermore National Laboratory. NARAC “provides tools and services that map the probable spread of hazardous material accidentally or intentionally released into the atmosphere“. The fuel pools at Units 3 and 4 contained enormous amounts of radiation. For example, there was “more cesium in that [Unit 4] fuel pool than in all 800 nuclear bombs exploded above ground.”
